LOCAL NETWORK AND METHOD FOR ESTABLISHING CONNECTION BETWEEN LOCAL GATEWAY AND HOME NODEB

摘要

The present invention discloses a local network and a method for establishing a connection between a local gateway and a home base station therein. As regards a newly proposed home base station network architecture 1, in embodiments of the present invention, a mobility management network element receives L-GW information sent by the home base station, selects an L-GW which is located in the same local network as the home base station at least according to the received L-GW information and then informs the L-GW, through an S-GW, of establishing a PDN connection and a tunnel bearer with the home base station, thereby providing a local IP access for a UE. As regards a newly proposed home base station network architecture 2, no direct interface is arranged between the L-GW and the S-GW, the mobility management network element directly selects a corresponding L-GW for establishing a PDN connection for the UE, providing a local IP access for the UE. The embodiments of the present invention is capable of establishing a tunnel connection between a home base station and an L-GW for a UE, so that data is routed from the L-GW to the home base station, rather than being transmitted indirectly through the core network of an operator.
